(Thomas Zambito) The pulverized remains of bodies from the World Trade Center disaster site were used by city workers to fill ruts and potholes, a city contractor says in a sworn affidavit filed yesterday in Manhattan Federal Court.

Eric Beck says debris powders – known as fines – were put in a pothole-fill mixture by crews at the Fresh Kills landfill on Staten Island, where more than 1.65 million tons of World Trade Center debris were deposited after the Sept. 11 attacks.

“I observed the New York City Department of Sanitation taking these fines from the conveyor belts of our machines, loading it onto tractors and using it to pave roads and fill in potholes, dips and ruts,” Eric Beck said.
